Sam Taylor earns 6 1/2% commission on sales of $4,226 as an advertising agent. What is his commission?

Final answer:

After 30 seconds, she will be 150 meters away.

Explanation:

To calculate how far the friend will be after 30 seconds on her bike, we must assume a constant velocity since no acceleration is mentioned. Given that she is 15 meters away after 3 seconds, we can calculate her velocity using the formula v = d/t, where v is velocity, d is distance, and t is time.

First, we find her velocity:

v = 15 m / 3 s = 5 m/s

Now that we have her velocity, we can calculate how far she will be after 30 seconds:

Distance = Velocity × Time = 5 m/s × 30 s = 150 m

Therefore, after 30 seconds, she will be 150 meters away.

Answer:

The bar diagram is shown below. Number of peoples who are 18 or older is 163,776.

Step-by-step explanation:

Given information:

Total number of peoples in the city = 332,054

Number of peoples who are under 18 = 168,278

Number of peoples who are 18 or older is

[tex]332,054-168,278=163,776[/tex]

We need to draw a bar diagram.

In the bar diagram x axis represents the age and y-axis represents the number of peoples.

First bar represents the number of peoples who are under 18 i.e., 168,278.

Second bar represents the number of peoples who are 18 or older i.e., 163,776.

divide cost by number of bottles

7/28 = 0.25 per bottle

check 28 * 0.25 = 7.00 

Joe's income was $40,200 in the 18th year.

To find the year in which Joe's income was $40,200, we need to determine the rate at which his income increases each year.

Given that his income increased by the same dollar amount each year, we can calculate the increase by subtracting his income in the first year from his income in the 11th year: $31,400 - $20,400 = $11,000.

Next, we can divide the increase in income by the number of years to find the increase per year: $11,000 ÷ 10 = $1,100.

Finally, to find the number of years it takes for his income to reach $40,200, we can divide the difference between $40,200 and $20,400 by the increase per year: ($40,200 - $20,400) ÷ $1,100 = 18.

Therefore, Joe's income was $40,200 in the 18th year.

Answer:

[tex](x^2 - x)[/tex] will always have an even value.

Step-by-step explanation:

We are given an integer x.

Let x be even, then it can be written in the form x = 2n, where n is an integer.

If we evaluate,

[tex](x^2 - x) = (2n)^2 - 2n = 4n^2 - 2n = 2(2n^2 - n)[/tex]

Thus, it have an even value.

If we take x to be an odd integer, then,it can be written in the form x = 2n+1, where n is an integer.

[tex](x^2 - x) = (2n+1)^2 - 2n = 4n^2 + 2n = 2(2n^2 + n)[/tex]

Thus, it have an even value.

Thus,

[tex](x^2 - x)[/tex] will always have an even value.

Answer:

[tex]3x^{4}-4x^{3}-8x^{2}-35x-10[/tex]

Step-by-step explanation:

We have been given that Vanessa uses the expressions [tex]3x^2+5x+10[/tex] and [tex]x^2-3x-1[/tex] to represent the length and width of her patio.

To find the expression that represents the area of Vanessa's patio we will multiply the length of patio by width of patio as:

[tex](3x^2+5x+10)*(x^2-3x-1)[/tex]

Upon using distributive property [tex]a(b+c)=a*b+a*c[/tex] we will get,

[tex](3x^2*x^2)+(3x^2*-3x)+(3x^2*-1)+(5x*x^2)+(5x*-3x)+(5x*-1)+(10x^2)+(10*-3x)+(10*-1)[/tex]

Using exponent property [tex]a^b*a^c=a^{b+c}[/tex] we will get,

[tex](3x^{2+2})+(-9x^{2+1})+(-3x^2)+(5x^{1+2})+(-15x^{1+1})+(-5x)+(10x^2)+(-30x)+(-10)[/tex]

[tex](3x^{4})+(-9x^{3})+(-3x^2)+(5x^{3})+(-15x^{2})+(-5x)+(10x^2)+(-30x)+(-10)[/tex]

[tex]3x^{4}-9x^{3}-3x^2+5x^{3}-15x^{2}-5x+10x^2-30x-10[/tex]

Now let us combine like terms.

[tex]3x^{4}-9x^{3}+5x^{3}-3x^2-15x^{2}+10x^2-5x-30x-10[/tex]

[tex]3x^{4}-4x^{3}-8x^{2}-35x-10[/tex]    

Therefore, the expression [tex]3x^{4}-4x^{3}-8x^{2}-35x-10[/tex] represents the area of Vanessa's patio.

Answer: [tex]u=x^6[/tex]

Explanation:

A quadratic equation is an equation written in the form

[tex]au^2 + bu + c=0[/tex] (1)

where a,b,c are coefficients and where u is the variable.

Our original equation is:

[tex]4x^{12} - 5x^6 -14=0[/tex]

If we make the substitution [tex]u=x^6[/tex], we obtain

[tex]4u^2 -5u-14 =0[/tex]

Which corresponds to eq.(1), with coefficients a=4, b=-5, c=-14.

Thanks for the explanation mate that was helpful^^

To determine the system of equations to which the ordered pair (3, –1) is a solution, we must find equations where substituting 'x' with 3 and 'y' with –1 produces true statements for both equations in the system.

The question pertains to finding the system of equations for which the ordered pair (3, –1) is a solution. To determine the correct system, we would need to identify equations that have both 'x' and 'y' variables. An ordered pair is composed of an 'x' coordinate and a 'y' coordinate, following the form (x, y). In this case, the 'x' value is 3, and the 'y' value is –1. If the ordered pair (3, –1) is a solution to a system of linear equations, it must satisfy both equations in the system. This means that when we substitute 'x' with 3 and 'y' with –1 into each equation, the equations should hold true.

For example, if we have a system of equations:

Substituting 'x' with 3 and 'y' with –1 into both equations, we get:

Since the ordered pair (3, –1) satisfies both equations, then (3, –1) is a solution to this system. To identify the system of equations the ordered pair belongs to, you would similarly test the pair in the given systems to see which one(s) it satisfies.

The recursive formula is an = a_(n-1) +4.

The correct option is (D).

A recursive formula refers to a formula that defines each term of a sequence using the preceding term(s). The recursive formulas define the following parameters:

The recursive formula to find the nth term of an arithmetic sequence is:

an = an-1 + d for n ≥ 2

where

an is the nth term of a A.P.

d is the common difference.

Given:

14, 18, 22, 26, 30, …

a1=14

and, d= 18-14

d=4

a2= a1 + 4

a2 = 14+4= 18

Similarly, going this way

an = a_(n-1) +4

Hence, the recursive formula is an = a_(n-1) +4

To determine the value(s) of h for a consistent linear system, the augmented matrix must not have any row that implies a contradiction, like 0x + 0y = c where c is non-zero. The exact values of h depend on the matrix itself and usually involve row reduction to identify non-contradictory solutions. The provided examples do not appear to relate directly to a linear system matrix.

To determine the value(s) of h that result in the matrix representing a consistent linear system, we must ensure that there are no contradictions within the augmented matrix. If the matrix represents a system of linear equations, consistency is achieved when the system has at least one solution. A contradiction would occur if a row in the augmented matrix had all zeros in the coefficient part and a non-zero value in the last column, corresponding to an equation like 0x + 0y = c (where c is non-zero), which has no solution.

The exact values of h would be determined by the context of the specific matrix and its elements, usually involving row reduction to echelon form to identify possible contradictions. In some cases, specific values of h can lead to a row of all zeros, which does not affect consistency, but a particular non-zero value in the rightmost column would create inconsistency. Without the explicit matrix, we cannot provide the exact values of h.

In the examples provided, it seems there is a mix of mathematical equations and expressions that are not directly related to a specific matrix or linear system. As such, the value of h in those expressions may refer to concepts like the uncertainty principle in quantum mechanics or gravitational force in physics, and thus do not pertain to solving a system of linear equations.

Answer:

2.99x + 12.99y = 43.92

Step-by-step explanation:

Here, x represents the number of pairs of socks purchased, and let y represents the number of blouses purchased.

Since, the cost of each pair of socks is $ 2.99 and the cost of a blouse is $ 12.99,

Thus, the total cost of x pairs of socks and y blouses = ( 2.99x + 12.99y ) dollars,

According to the question,

Total cost is $43.92,

⇒ 2.99x + 12.99y = 43.92

Which is the required equation.
